Directed by award-winning filmmaker Jennifer Baichwal and renowned photographer Edward Burtynsky, Watermark brings together diverse stories from around the globe about our relationship with water: how we are drawn to it, what we learn from it, how we use it and the consequences of that use. We see massive foating abalone farms off China's Fujian coast and the construction site of the biggest arch dam in the world - the Xiluodu, six times the size of the Hoover. We visit the barren desert delta where the mighty Colorado River no longer reaches the ocean, and the water-intensive leather tanneries of Dhaka. We witness how humans are drawn to water, from the U.S. Open of Surfing in Huntington Beach to the Kumbh Mela in Allahabad, where thirty million people gather for a sacred bath in the Ganges at the same time. We speak with scientists who drill ice cores two kilometers deep into the Greenland Ice Sheet, and roam the sublime pristine watersheds of Northern British Columbia. Shot in stunning 5K ultra high-definition video and full of soaring aerial perspectives, this film shows water as a terraforming element and the scale of its reach, as well as the magnitude of our need and use. This is balanced by forays into the particular: a haunting memory of a stolen river, a mysterious figure roaming ancient rice terraces, the crucial data hidden in a million year old piece of ice, a pilgrim's private ritual among thousands of others at the water's edge. Watermark is the third part of Burtynsky's Water project, which includes a book Burtynsky: Water (Steidl Publishers) and a photographic exhibition in London at Flowers gallery, 5 September - 4 October. Filmed and produced by Nicholas de Pencier and three years in the making, it is a logical extension of the trio's previous collaboration, Manufactured Landscapes. In Watermark, the viewer is immersed in a world defined by a magnificent force of nature that we all too often take for granted - until it's gone. Watermark was awarded Best Feature Documentary at the Canadian Screen Awards and the Best Canadian Film Award at the Toronto Film Critics Association's Awards.
